Abstract
The hygrometric behaviour of four artificial stone materials utilised in the building industry for thermal insulation has been investigated utilising analytical methods typical of the applied petrography. The experimental data on the water absorption both in the liquid and in the vapour phase are in agreement with the data obtained from the natural stone materials and point out the existence in each material of a strong correlation between the absorption mechanisms and the porosimetric characteristics.
Résumé
On a étudié, à l’aide de méthodes analytiques utilisées en pétrographie appliquée, le comportement hygrométrique de quatre matériaux pierreux artificiels utilisés dans l’industrie du bâtiment pour leurs propriétés d’isolants thermiques. Les données expérimentales sur l’absorption d’eau aussi bien à l’état liquide qu’à l’état de vapeur, sont en accord avec les données obtenues sur les matériaux pierreux naturels, c’est-à-dire que dans chaque matériel il y a de fortes corrélations entre les mécanismes d’absorption d’eau et les caractéristiques porosimétriques.
